The order, worth nearly é1m, will propel sales in the year to the end of February to é8m, said finance director Anthony Harris. Pre-tax profits are expected to come in at é450,000.

With a strong order book, he is confident that Vaclensa will hit the é10m mark within the next two years. The company, based on the Wardley Industrial Estate, manufactures equipment as well as importing.

The company distributes commercial vacuum cleaners, steam cleaners, sweepers and polishers, and provides after-sales servicing. It employs more than 120 people.

Vaclensa's range also includes tub vacuum cleaners - it sells around 10,000 of them a year to retailers, pub and leisure chains - and recently bought a large amount of tooling equipment to cut costs and give it control over product development.

The purchase was supported by Lloyds TSB Corporate Markets , whose director Anne Gillbard said: "The supermarket deal is the latest major contract win, which as come about through excellent product development and competitive pricing.

"Vaclensa has also worked extremely hard to build up a respected and trusted brand, and this too is paying dividends.

"We're confident that this investment will help management further a very successful product and grow market share."
